On Jewellery explores different themes, such as Conceptual Jewellery, Jewellery and Photography, Borderline Jewellery and the Language of Jewellery. It deals with assumptions, definitions, prejudices and claims, to take up a position and with the aim to describe the field in its full richness, and within the context of society and fine art. The book covers the period from the late 1960s until the present day with examples chosen from all around the world. Jewellers today have the potency and feel the need to express themselves in a large range of different mediums. The use of traditional materials, techniques and methods, once questioned, has now become a matter of content and conceptualisation. New techniques have also become available, like video, book, or performances that are used to unveil mechanisms, and to research and reflect on jewellery as a social, emotional and artistic phenomenon and as an everyday object. This is a synopsis of what art jewellery is or can be, that aims to disclose its idiosyncrasies, language and potency.
